The front camera on my HTC One X was pretty good when it came back from the HTC repair centre. It was clear than it had ever been and i was impressed. However, after 2 weeks, the front camera has gone terrible. Really grainy and blurry. I've tried cleaning the camera with a microfibre cloth and cotton buds however, no different. There is no visible damage or dust on I don't know why it's so bad. Any ideas? I've included 2 pictures taken with the front camera
